Description

Technical Field

[0001] This utility model relates to the field of paper box production technology, and in particular to a paper box positioning mechanism for a gluing machine. Background Technology

[0002] In the packaging and printing industry, the application of box gluing machines is the final process in packaging box processing. It involves folding and gluing printed and die-cut cardboard into shape. Machine gluing replaces manual gluing, reducing labor costs and improving efficiency. The box gluing machine is divided into a paper feeding section, a pre-folding section, a bottom hook section, a forming section, and a box pressing section.

[0003] Application No. 202021407048.1 discloses a carton positioning mechanism for a carton gluing machine, which solves the problem that tilting or lateral displacement of the carton during the paper output process causes subsequent action mechanisms to fail to accurately position the carton, thus affecting the yield. The positioning plates used for side limiting are mainly adjusted by a lead screw to change the spacing between the positioning plates to accommodate different carton sizes, and the movement of the carton is assisted by the rolling of auxiliary rollers. However, the accuracy of the lead screw will be affected over long-term use, and the auxiliary rollers will continuously rub against the outer circumference of the carton during rolling, which may excessively compress the carton and damage its flatness, reducing the quality of carton production. Utility Model Content

[0004] This utility model discloses a carton positioning mechanism for a carton gluing machine, aiming to solve the technical problems that the accuracy of the lead screw will be affected by long-term use, and the auxiliary roller will continuously rub against the outer periphery of the carton during the rolling process, which may result in excessive compression of the carton and damage to the flatness of the carton, thus reducing the quality of carton production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A carton positioning mechanism for a carton gluing machine includes a conveyor belt, a bidirectional lead screw assembly disposed at the bottom end of the conveyor belt, two track wheel assemblies movably connected to the bidirectional lead screw assembly, a positioning mechanism disposed between the two track wheel assemblies, an auxiliary observation mechanism disposed on the positioning mechanism, and an auxiliary positioning mechanism.

[0007] The positioning mechanism includes a first support frame, a screw tube movably connected to the first support frame, a first gear fixedly connected to the outer periphery of the screw tube, a second gear meshing with the first gear, a support rod fixedly connected to the second gear, a turntable fixed to one end of the support rod, two screws symmetrically meshing with the screw tube, a first support plate fixed to the outer end of each screw, an outer sleeve and an inner support rod connected to opposite sides of the two first support plates;

[0008] Each of the bidirectional lead screw assemblies has two first sliders symmetrically meshing, and each first slider has a side frame fixedly connected to its outer wall, and each side frame is connected to the track wheel assembly.

[0009] The inner wall of the first support frame is provided with a first limiting hole and a second limiting hole. The screw tube is movably connected to the second limiting hole, and two circular limiting plates are fixedly connected to the outer periphery of the screw tube. The two circular limiting plates are respectively movably attached to both sides of the first support frame.

[0010] The inner support rod is movably fitted against the inner wall of the outer sleeve, and one end of the support rod is connected to a first bearing seat, which is fixedly connected to one side of the outer wall of the first support frame.

[0011] By incorporating a positioning mechanism, the entire conveying structure features tracked wheel sets on both sides, providing positioning for the sides of the cardboard box. This allows the cardboard box to maintain a relatively static contact with the tracked wheel sets, reducing friction with the outer wall of the cardboard box and preventing damage to its sides. The positioning mechanism also allows for changing the total length of the two screws by rotating a turntable. This, in turn, provides internal support between the two side frames by aligning the total length with the length of the cardboard box. Even if the bidirectional screw assembly experiences reduced movement accuracy over long-term use, the positioning mechanism prevents the cardboard box from being squeezed.

[0012] In a preferred embodiment, the auxiliary positioning mechanism includes a longitudinal slide groove, a third slider movably connected within the longitudinal slide groove, a pointer fixedly connected to one side outer wall of the third slider, a second support frame fixedly connected to one side outer wall of the first support frame, and a vortex slide groove connected to the outer wall of the second support frame.

[0013] The longitudinal slide is fixedly connected to the outer wall of the support rod, and a guide slide rod is fixedly connected to one side of the outer wall of the third slider, with the guide slide rod located directly below the pointer.

[0014] The guide slide rod is movably connected to the vortex slide groove, and a marking is correspondingly provided on one side of the outer wall of the vortex slide groove;

[0015] The second support frame and the vortex groove are both provided with through holes, and the support rod passes through the through holes, with its outer wall movably fitting against the inner wall of the through holes.

[0016] With the auxiliary positioning mechanism, the guide rod and pointer move along the longitudinal groove under the limiting action of moving within the vortex groove during the rotation of the support rod. The value pointed to by the pointer represents the distance between the two track wheel sets. Therefore, when manually adjusting the distance between the track wheel sets, the appropriate spacing can be adjusted by observing the value pointed to by the pointer to adapt to the use of different sizes of cardboard boxes, thereby reducing the difficulty of manual adjustment.

[0017] In a preferred embodiment, the auxiliary observation mechanism includes a second support plate fixedly connected to the outer wall of one side of the second support frame, a damping groove through the second support plate, a second damping bearing seat movably connected in the damping groove, and a mirror hinged in the second damping bearing seat.

[0018] A second damping slider is movably disposed within the damping groove, and the second damping slider is connected to a second damping bearing seat. The mirror surface is connected to the second damping bearing seat via a hinge rod.

[0019] By incorporating an auxiliary observation mechanism, the pointing and matching results of the pointer and indicator can be observed through a mirror. The mirror's angle can be changed by moving the second damping slider within the damping groove to adapt to different pointer positions. Furthermore, the mirror's angle can be rotated through the connection between the second damping bearing seat and the hinge rod to accommodate different observation positions, thereby preventing component obstruction from affecting the numerical observation.

[0020] As described above, a carton positioning mechanism for a carton gluing machine includes a conveyor belt, a bidirectional lead screw assembly disposed at the bottom end of the conveyor belt, two track wheel assemblies movably connected to the bidirectional lead screw assembly, a positioning mechanism disposed between the two track wheel assemblies, an auxiliary observation mechanism disposed on the positioning mechanism, and an auxiliary positioning mechanism. The positioning mechanism includes a first support frame, a screw tube movably connected within the first support frame, a first gear fixedly connected to the outer circumference of the screw tube, a second gear meshing with the first gear, a support rod fixedly connected to the second gear, a turntable fixed to one end of the support rod, two screws symmetrically meshing within the screw tube, a first support plate fixed to the outer end of each screw, and an outer sleeve and an inner support rod connected to opposite sides of the two first support plates. The carton positioning mechanism for a carton gluing machine provided by this utility model has the technical effect of providing positioning for the carton while avoiding damage to the carton.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] The paper box positioning mechanism of the gluing machine disclosed in this utility model is mainly used in the scenario of paper box positioning in the gluing machine.

[0028] Reference Figures 1-3 A carton positioning mechanism for a carton gluing machine includes a conveyor belt 1, a bidirectional lead screw assembly 6 disposed at the bottom end of the conveyor belt 1, two track wheel assemblies 2 movably connected to the bidirectional lead screw assembly 6, a positioning mechanism 3 disposed between the two track wheel assemblies 2, an auxiliary observation mechanism 4 disposed on the positioning mechanism 3, and an auxiliary positioning mechanism 5.

[0029] The positioning mechanism 3 includes a first support frame 301, a screw tube 306 movably connected within the first support frame 301, a first gear 304 fixedly connected to the outer periphery of the screw tube 306, a second gear 311 meshing with the first gear 304, a support rod 310 fixedly connected to the second gear 311, a turntable 309 fixed to one end of the support rod 310, two screws 307 symmetrically meshing within the screw tube 306, a first support plate 308 fixed to the outer end of each screw 307, an outer sleeve 313 connected to the opposite side of the two first support plates 308, and an inner support rod 314. In the entire conveying structure, by providing track wheel sets 2 on both sides, which contact the sides of the cardboard box to convey the cardboard box, the positioning function of the sides of the cardboard box can be provided. Compared with directly using rollers or other structures to limit the sides of the cardboard box, this allows the cardboard box to be positioned by the track wheel. The wheel assembly 2 is in relatively static contact, which reduces friction with the outer wall of the cardboard box to prevent damage to both sides of the box. At the same time, the distance between the two track wheel assemblies 2 can be changed by the bidirectional screw assembly 6. Under the action of the positioning mechanism 3, the rotating turntable 309 drives the second gear 311 and the first gear 304 through the support rod 310 to rotate the screw tube 306 within the first support frame 301. Based on the limiting effect of the outer tube 313 and the inner support rod 314, the two screws 307 can move in opposite directions, changing the total length formed by the two screws 307. Thus, by making the total length correspond to the length of the cardboard box, internal support is provided between the two side frames 8. In this structure, even if the bidirectional screw assembly 6 reduces the movement accuracy after long-term use, the positioning mechanism 3 can prevent the cardboard box from being squeezed.

[0030] Reference Figure 3 In a preferred embodiment, each bidirectional lead screw assembly 6 has two first sliders 7 symmetrically engaged, and each first slider 7 has a side frame 8 fixedly connected to its outer wall, and each side frame 8 is connected to the track wheel assembly 2.

[0031] Reference Figure 3 In a preferred embodiment, the inner wall of the first support frame 301 is provided with a first limiting hole 302 and a second limiting hole 303. The screw tube 306 is movably connected to the second limiting hole 303, and two circular limiting plates 305 are fixedly connected to the outer periphery of the screw tube 306. The two circular limiting plates 305 are respectively movably attached to both sides of the first support frame 301.

[0032] Reference Figure 3 In a preferred embodiment, the inner support rod 314 is movably fitted against the inner wall of the outer sleeve 313, one end of the support rod 310 is connected to the first bearing seat 312, and the first bearing seat 312 is fixedly connected to one side of the outer wall of the first support frame 301.

[0033] Reference Figure 4In a preferred embodiment, the auxiliary positioning mechanism 5 includes a longitudinal slide groove 503, a third slider 508 movably connected in the longitudinal slide groove 503, a pointer 502 fixedly connected to one side outer wall of the third slider 508, a second support frame 507 fixedly connected to one side outer wall of the first support frame 301, and a vortex slide groove 505 connected to the outer wall of the second support frame 507.

[0034] Reference Figure 4 In a preferred embodiment, the longitudinal groove 503 is fixedly connected to the outer wall of the support rod 310, and a guide rod 501 is fixedly connected to one side of the outer wall of the third slider 508, and the guide rod 501 is located directly below the pointer 502.

[0035] Reference Figure 4 In a preferred embodiment, the guide rod 501 is movably connected to the vortex groove 505, and a marking 504 is correspondingly attached to one side of the outer wall of the vortex groove 505.

[0036] Reference Figure 4 In a preferred embodiment, the second support frame 507 and the volute groove 505 are both provided with through holes 506, and the support rod 310 passes through the through hole 506, with its outer wall movably fitting against the inner wall of the through hole 506. In the auxiliary positioning mechanism 5, as the manual control turntable 309 drives the support rod 310 to move, the distance of the positioning mechanism 3 is changed. During the rotation of the support rod 310, and under the limiting action of the guide slide rod 501 moving within the volute groove 505, the guide slide rod 501 and the pointer 502 are driven. Moving along the longitudinal slide 503, the pointer 502 is marked with a distance value corresponding to the rotation distance of the support rod 310. Under the limiting action of the guide slide rod 501 and the longitudinal slide 503, the value pointed to by the pointer 502 on the mark 504 represents the distance between the two track wheel sets 2. Therefore, when manually adjusting the distance between the track wheel sets 2, the appropriate spacing can be adjusted by observing the value pointed to by the pointer 502 to adapt to the use of different sizes of cardboard boxes, thereby reducing the difficulty of manual adjustment.

[0037] Reference Figure 3 and Figure 4 In a preferred embodiment, the auxiliary observation mechanism 4 includes a second support plate 403 fixedly connected to the outer wall of one side of the second support frame 507, a damping groove 406 extending through the second support plate 403, a second damping bearing seat 402 movably connected within the damping groove 406, and a mirror 401 hinged within the second damping bearing seat 402.

[0038] Reference Figure 3 and Figure 4In a preferred embodiment, a second damping slider 405 is movably disposed within the damping groove 406, and the second damping slider 405 is connected to the second damping bearing seat 402. The mirror surface 401 is connected to the second damping bearing seat 402 via a hinge rod 404. In the auxiliary observation mechanism 4, the pointing matching result of the pointer 502 and the indicator 504 can be observed through the mirror surface 401. The movement of the second damping slider 405 within the damping groove 406 can change the corresponding angle of the mirror surface 401 to adapt to the pointer 502 in different positions. Through the connection between the second damping bearing seat 402 and the hinge rod 404, the angle of the mirror surface 401 can be rotated to adapt to different observation positions, thereby avoiding component obstruction from affecting the numerical observation.

[0039] Working principle: In the entire conveying structure, tracked wheel sets 2 are set on both sides to convey the paper box by contacting the sides of the paper box. This provides positioning for the sides of the paper box. Compared with directly using rollers or other structures to limit the sides of the paper box, this allows the paper box to have a relatively static contact with the tracked wheel sets 2, reducing friction with the outer wall of the paper box and preventing damage to the sides of the paper box. At the same time, the distance between the two tracked wheel sets 2 can be changed by the bidirectional screw set 6. Under the action of the positioning mechanism 3, the rotating turntable 309 is connected by the support rod 310. The second gear 311 and the first gear 304 drive the screw tube 306 to rotate within the first support frame 301. Based on the limiting effect of the outer sleeve 313 and the inner support rod 314, the two screws 307 can move in opposite directions, changing the total length formed by the two screws 307. Thus, by making the total length correspond to the length of the carton, internal support is provided between the two side frames 8. Under this structure, even if the movement accuracy of the bidirectional lead screw assembly 6 decreases after long-term use, the positioning mechanism 3 can prevent the carton from being squeezed.

[0040] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
